Steps to reproduce:1. Create two sprites ("buttons") looking exactly the same with twosimilar animation frames each2. add the sprites to a family3. Create an event that makes one sprite in the family change toanimationframe 1 (instead of 0) when the mouse is over the sprite, and one for the exact opposite (when the mouse is not over the sprite, the animation goes back to frame 0)

Observed result:Both sprites flicker to animationframe 1 upon the mouse hoovering over one of the sprites (only the first time it occurs in the session)

Expected result:Only the sprite that the mouse is over should change animationframe

Closing as not a bug. The animation speed is 5, so the other object proceeds with its animation once "mouse not over button" is not true (since the mouse is not over the other object). Works if you set the animation speed to 0.
